Convert INO to CPP

QUICK ANSWER
Is it possible to convert INO to CPP?
Yes - INO converts to CPP.

A sketch is already C++. To turn it into standalone .cpp/.h you add the headers the Arduino build adds automatically (#include <Arduino.h>, function prototypes) - the Arduino IDE/CLI can export the preprocessed code, or you rename and add boilerplate by hand. Mostly relevant when moving to PlatformIO or pure C++.
